摘要： A hollow frame member is constituted by joining with a truss shape by ribs 13, 13A, 13B (23, 23A, 23B) between two face plates 11, 12 (21, 22). An end portion of one of the hollow frame member 10 is connected according to the rib 13A for constituting the truss. A face plate 21 of another hollow frame member 20 is joined at a vicinity of an apex of the truss of the hollow frame member 10. A face plate of the hollow frame member 10 is joined at a vicinity of an apex of the truss of the another hollow frame member 20. A load during a friction stir joining is received according to the ribs 13A, 13B (13A, 23B). Since the truss structure is formed totally, the light weight structure and the high rigidity performance can be obtained.

摘要： When an insertion force of a rotary tool 340 has searched, it is made clearly that the force at the insertion initial time is large and when a friction stir joining is an ordinary operation time, the force becomes small. According, it is preferable to make small the insertion force at the insertion initial time. To members 20, 30 to be subjected to a joining at a position where the friction stir joining starts a hole 50 is opened, and this hole 50 after the rotary tool 340 has inserted, since a move of the rotary tool 340 is made to begin, a lowering of the insertion force can be attained.

摘要： The present invention aims to provide a joint figuration inhibiting decrease in strength resulting from welding at the joint region, in a case where hollow-shaped material is friction stir welded. A face plate 101 (111) between a rib 105 (115) at the end portion of a hollow-shaped material 100 (110) and a rib 103 (113) has a thickness t2 (t5) at the rib 105 (115) side and ti at the rib 103 (113) side. The thickness t2 (t5) is thicker than ti. The thickness between the two is changed smoothly. The thickness of the plate thickness t2 (t5) is provided by projecting towards the other face plate side.

摘要： The invention provides a transportation device having a shock absorbing device with a reduced non-collapse region. Shock absorbers 14 and 17 constituting a shock absorbing device 10A provided on a transportation device is connected respectively to shock absorbers 17 and 20 disposed rearward therefrom via connecting members 23 and 26 having ashtray-like cross-sectional shapes. The shock absorber 20 disposed at the rearmost position is connected via welding to a base 29. Collapse regions 15, 18 and 21 of the shock absorbers 14, 17 and 20 are collapsed by the load applied to the shock absorbers 14, 17 and 20, and their lengths are shortened. Non-collapse regions 16 and 19 of the shock absorbers 14 and 17 overlap respectively with the non-collapse regions 19 and 22 of the shock absorbers 17 and 20 disposed rearward therefrom. Therefore, the non-collapse regions 16, 19 and 22 fit within a recessed portion of the connecting members 23 and 26, and the overall longitudinal length of the non-collapse regions of the shock absorbing device can be shortened.

摘要： The invention provides a car body of a railway vehicle capable of absorbing the energy caused when collision occurs to the end of the car body. The present invention comprises a strength member 15 disposed along the circumferential direction of the car body on the end of the car body, a strength member 16 disposed along the circumferential direction at a position rearward from the member 15, rib members 17 disposed along the longitudinal direction of the car body and connecting the two strength members, and an outer panel 18 covering the same. The longitudinal direction of the rib member 17 corresponds to the longitudinal direction of the car body. The rib member 17 is composed of two flanges 17c, 17d and a web 17b connecting the two flanges, and the side having the web 17b is welded to the outer panel 18 via fillet welding. A notch 21 opened to the edge of the flange is formed on the flange at the center of the longitudinal direction of the rib member 17. When collision load is applied, the notch 21 is valley-folded, by which the rib member is bent toward the direction opposite from the side to which the outer panel 18 is attached, so that the collision load can be absorbed sufficiently since the outer panel 18 will not interfere with the buckling of the rib member 17.
